I will use memmove for unaligned access and release libs and utils tomorrow or the day after tomorrow.

CSR firmware question...

Hi guys, A few questions regarding CSR firmware : what's a commonly available BT USB dongle with a recent CSR firmware. Long story : I'm hitting various bugs with the CSR firmware in my D-Link USB dongles (0x1bb), where I can easilly deadlock the dongle. My 3Com dongle, which has a more recent firmware (0x20e), behave much better, but not perfect. D-Link doesn't provide a firmware updater, but, beeing fearless, I tried to firmware upgrade a D-Link dongle and ended up with a dead dongle (can't even put back the original firmware on it). From the release notes, the latest CSR firmwares have zillions of bug fixes. I really wonder how I can enjoy the bug fixes. Thanks in advance... Jean P.S. : Marcel, do you have a version of btdfu that can write the firmware image to the dongle ? Or some documentation ? ------------------------------------------------------- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285

Show us the outputs of "hciconfig -a" for both devices.
